Index Table Indexing
- Setting for positioning the index table
#7 #6 #5 #4 #3 #2 #1 #0
5500 IDX SIM G90 INC ABS REL DDP
[Data type] Bit path
#0 DDP Selection of a decimal point input method for an index table indexing axis
0 : Conventional method (Example IS-B: B1; = 0.001 deg)
1 : Calculator method (Example IS-B: B1; = 1.000 deg)
#1 REL Relative position display of index table indexing axis
0 : Not rounded by 360 degrees
1 : Rounded by 360 degrees
#2 ABS Displaying absolute coordinate value of index axis
0 : Not rounded by 360 degrees
The index axis rotates 720 degrees (two rotations) when G90 B720.0; is
specified from the 0-degree position. It rotates in reverse direction
720 degrees (two rotations) when G90 B0.; is specified. The absolute
coordinate value then becomes 0 degree.
1 : Rounded by 360 degrees
The index axis is positioned to 40 degrees when G90 B400.0; is
specified from the 0-degree position. The index axis does not rotate
by two or more turns when this parameter is set to 1. It also does not
move when G90 B720.0; is specified from the 0-degree position.
#3 INC Rotation in the G90 mode. This applies when negative direction M-code
(parameter No. 5511) is not set
0 : Not set to the shorter distance around the circumference
1 : Move the shorter distance around the circumference (Set ABS, #2 of
parameter No. 5500, to 1.)
#4 G90 Index table indexing command
0 : An absolute/increment command according to the G90/G91 mode
1 : Always an absolute command
#6 SIM When the same block includes a command for an index table indexing axis
and a command for another controlled axis:
0 : An alarm (PS0136) is issued.
1 : The commands are executed. (In a block other than G00, G28, and
G30, however, an alarm (PS0136) is issued.)
#7 IDX Index table indexing sequence
0 : Type A
1 : Type B
